DESCRIPTION

Also known as PORB_ZOBGA, porB. Cleaves the sulfated polysaccharide porphyran at the (1->4) linkages between beta-D-galactopyranose and alpha-L-galactopyranose-6-sulfate, forming mostly the disaccharide alpha-L-galactopyranose-6-sulfate-(1->3)-beta-D-galactose. Some longer oligosaccharides of even number of residues are also observed. Inactive on the non-sulfated agarose portion of the porphyran backbone. In contrast to PorA, tolerates the presence of 3-6-anhydro-L-galactose in subsite -2.
